I really don't understand the Dynamic Queue hatred
My ranked experience has been TREMENDOUSLY more positive since dynamic queue was implemented. I can't even remember the last time I had an afk which I had all the time in season 5.
People say they don't like it because they don't like facing pre mades but I don't understand this logic. According to riot, 98% of 4 people pre mades are matched with other 4 people pre mades and 5 man pre mades are matched with other 5 man pre mades 96% of the time.
So assuming you're not in the 4% getting matched against 5 man pre mades (which you may just be the odd ball out in a 4 man pre made which really isn't too much of a disadvantage anyway) here's the part where I'm unsure why people hate dynamic queue. You have just as much chance of being put on a team with a bad 4 man pre made as you do a good 4 man premade. Likewise, the other solo player also has this same chance.
It appears that the chances of your team being good or bad are the same as they were before dynamic queue because pre mades are typically matched against other pre mades. This is why I personally love dynamic queue.
